Manufacturer names are tied to specific countries (on Y50), and frequently, models (on y61, y62) are discovered to be assigned under a manufacturer for the wrong country since many of the SAME manufacturing companies operate out of multiple countries. Duplication of this type is normally accounted for on the manufacturer table by suffixing with country designations (example : PRATT & WHITNEY - CAN , PRATT & WHITNEY - USA )
